Introduction

The emissions from preservative treated wood to the environment need to be quantified to enable an

environmental risk assessment of the treated wood. This document describes a laboratory method for the

estimation of emissions from preservative treated wood in the case where the preservative treated wood is not

covered by a physical protection and is in contact with the ground, fresh water or seawater. There are three

situations in this case where emissions could enter the environment:

a) emissions from treated wood in contact with the ground. Use Class 4A. Emissions from the surface of the

treated wood could enter the soil via the soil water;

b) emissions from treated wood in contact with fresh water. Use Class 4B. Emissions from the surface of the

treated wood could enter the water;

c) emissions from treated wood in contact with sea water. Use Class 5. Emissions from the surface of the

treated wood could enter the sea.

The method is a laboratory procedure for obtaining water samples (leachate) from treated wood in contact

with water, at increasing time intervals (complete duration of 29 days). The quantities of emissions in the

leachate are related to the surface area of the wood and the length of exposure, to estimate a flux in

milligrams per square metre per day.

The quantity of emissions can be used in an environmental risk assessment of the treated wood.

1 Scope

This Technical Specification specifies a laboratory method for obtaining water samples from treated wood

which has been in conditions designated to simulate continuous contact with the ground or with water (use

Class 4 or 5), at time intervals after exposure.
2 Description of the test method
2.1 General considerations

The principal agent for causing emissions from wood exposed to soil is the soil water. The mechanism of

leaching at the wood surface by the soil water is assumed to be identical in nature and severity to leaching

from a wood surface in continuous contact with water.

The mechanism of leaching at the wood surface by fresh water is assumed to be identical in nature and

severity to leaching from a wood surface by seawater.

The wood, in the case of wood treated with a wood preservative, shall be representative of commercially used

wood. It shall be treated in accordance with the preservative manufacturer’s instructions and in compliance

with appropriate standards and specifications. The parameters for the post-treatment conditioning of the wood

prior to the commencement of the test shall be stated.

The composition, amount and pH value of the water used in the test are important in determining the quantity,

content and nature of emissions from wood.
2.2 Principle

Water samples are collected after continuous contact with treated wood at increasing time intervals. To

simulate the emission of wood preservatives from wood that is exposed to continuous contact with water test

specimens are immersed in water and samples of the water are collected at different intervals. The volume of

water relative to the surface area exposed to the water is equivalent to the ratio found in wood exposed in

3 2 2

service in some Use Class 4 situations (1 m per 40 m or 25 l per m ). The water (leachate) is collected and

is chemically analysed at seven or more sample times over the 29 days; it is suitable for ecotoxicity testing.

Emission rates in milligrams per square metre per day are calculated from analytical results. The sampling

periods are recorded. Tests with untreated samples can be discontinued if there is no background detected in

the first three data points.
2.3 Quality criteria
2.3.1 Accuracy

The performance of the analytical method should be determined before conducting the test:

1) Accuracy;
2) Specificity;
3) Limit of detection;
4) Limit of quantification.
The testing is carried out with untreated references and with controlled water.

CEN/TS 15119-2:2012 (E)
2.3.2 Reproducibility

Two water samples are collected and analysed and the mean value is taken as the emission value. The

reproducibility of the results within one laboratory and between different laboratories depends upon the

immersion regime and the wood used as test specimens.
2.4 Product and reagent
2.4.1 Water

Fresh water and soil leaching scenarios: Water complying with grade 3 of EN ISO 3696 or water especially

designed for environmental investigations is ideal. Deionised water can also be used. The pH value shall

normally be in the range 5 to 7. The pH value shall not be adjusted unless special conditions might justify

setting the pH to a specified value between 5 and 7.

Water temperature shall be (20 ± 2) °C. The pH value and water temperature shall be stated in the test report.

2.4.2 Seawater

Seawater leaching scenarios: Synthetic seawater (e.g., ASTM D 1141 Substitute Ocean Water, without Heavy

Metals) is recommended for use in the leaching test when wood exposed to seawater is to be evaluated. The

water temperature shall be (20 ± 2) °C and the measured pH and water temperature included in the test

report.
2.4.3 Preservative

The identity of the preservative product used to treat the wood samples shall be stated in the test report. It

shall state the name and other designation of the preservative, and the trade or common name of the active

ingredient(s), substances of concern (as defined in the EU Directive 98/8/EC) or a generic description of co-

formulates and the composition expressed in terms of the mass fraction of each of the ingredients.
